through things like dm-verity.

This introduces a new syscall (currently only on x86), similar to
init_module, that has only two arguments. The first argument is used as
a file descriptor to the module and the second argument is a pointer to
the NULL terminated string of module arguments.


Please use the standard naming convention, which is an f- prefix (i.e. finit_module()).
